Every day, thousands of cargo ships around the world are busy loading and unloading their cargo. In addition to their intended cargo, however, these enormous vessels also ship other, unintended cargo. Hidden in the ships' ballast water - water used to stabilize the ships when not carrying a load - and stuck to the ships' hulls, millions of tiny plants and animals are also making their way around the world. These non-native organisms are released with ballast water into a new port during loading and unloading of cargo or are scraped off the hull. Though not all survive the big trip, some do, and even adapt well to the environment. Some do so well that they out-compete local species, and others introduce diseases that quickly spread through the ecosystem.

Many Americans are surprised to learn that women once played professional baseball in the All-American Girls Professional Baseball League (AAGPBL) from 1943-1954. Founded by Chicago Cubs owner Phil Wrigley in order to entertain Americans - and keep ballparks full - during World War II, the league provided unprecedented opportunity for young women to play professional baseball, see the country, and aspire to careers beyond the traditional roles of teacher, secretary, nurse, librarian, or housewife.

Take a front row seat on the wooden bleachers of a wind-swept-field where baseball provides a virtual view of our country's character. Journey back in time to discover a young land as its enterprising soul comes of age in the villages and towns of 19th century America. Follow the exploration of a western frontier after an anguishing Civil War to see how natives and naturalized citizens forge a familiar pastime while learning each other's customs and cultures.

Presidential campaigns are different now. People no longer come to the candidate's home. Instead, the candidate comes to the homes of the people; his picture and message are beamed into millions of bedrooms and kitchens. The notepad and pencil are gone, replaced by computers and phone lines, video cameras, and satellites. The most important thing has not changed. This year, as every four years from the beginning of the republic, candidate and press will be joined - often suspiciously, sometimes in hostility - but always from the necessity as essential partners in the quadrennial dance of democracy.

What good are caves? In a practical sense, they are nature's plumbing system and homes to many animals. For people with various needs, values and levels of curiosity, caves provide places for adventure, shelter, and cutting-edge research. Discoveries made in caves offer us a glimpse into the past and the future and continue to lead us into future exploration. The National Park Service protects 81 sites that contain over a thousand limestone caves and lava tubes. About a dozen sites offer tours where park visitors enjoy scenic views made up of slow-growing speleothems - what you may know as stalactites, stalagmites, cave bacon, etc. Visitors also marvel at the fish, bats and insects that call caves home, but it is microbes that are a main form of life in caves. By studying bacteria that exists underground, scientists are gaining a better understanding of how biology shapes our world and influences geology. Cave microbes may hold a key to a cure for cancer or may help us recognize life on Mars. Caves also preserve evidence of ancient cultures, such as pictographs and stone tools, and keep alive the spirit of exploration through the stories of past and current explorers.

Have you ever wondered about those raised red, cotton stitches on a baseball? Sure, they hold the cowhide cover together, but did you know they also teach an interesting lesson in aerodynamics? What goes up must come down; that's why velocity, air temperature, gravity, and altitude are all fascinating factors in a batter's ability to launch a longball. Catching up to a pitch hurled at 100 miles per hour and sending it into orbit is a surprisingly scientific feat. Join us in Jupiter, Florida, where spring training 2004 becomes both classroom and clinic to explore physics and nature through our National Pastime.

During this electronic field trip, experienced museum educators will use the artifacts and stories in the United States Holocaust Memorial Museum's permanent exhibition, The Holocaust, to help students explore the Nazi rise to power and how countless individuals, traditionally relied upon to uphold the public good, became the active participants in civil rights violations and mass murder. Through the lens of history, students will then be asked to explore the consequences of their own daily decision making, both on their immediate environment and the world at large.

As airplanes fly, they push air out of the way and force it into taking different paths. That pushed air must go somewhere, so it "squeezes" between the wings and surrounding air. Explore the concepts of Air, Bernoulli, Wings and airplane design. Students will be taken through the "How Things Fly" exhibit at the Smithsonian National Air and Space Museum.

Grand Canyon is considered the finest example of arid-land erosion in the world; however, it is more than that. A significant portion of Earth's history is revealed within the exposed rock layers of the canyon, five of the seven life zones in North America are represented within the park and it has been home to humans for nearly 10,000 years. Come explore some of the 1,217,403 acres of Grand Canyon National Park - hike into the canyon with Park Rangers, investigate fossils of animals that lived 270 million years ago, learn about the diversity of plants and animals that inhabit this semi-arid environment and explore the ruins of ancient inhabitants.
